This study investigated the effect of low-intensity aerobic training combined with blood flow restriction (LABFR) on body composition, physical fitness, and vascular functions in recreational runners. The participants were 30 healthy male recreational runners, randomized between the LABFR (n = 15) and control (n = 15) groups. The LABFR group performed five sets of a repeated pattern of 2 min running at 40% VO2max and 1 min passive rest, while wearing the occlusion cuff belts on the proximal end of the thigh. The frequency was three times a week for the period of eight weeks. The control group performed the identical running protocol without wearing the occlusion cuff belts. At the end of the training, the participants’ body composition (fat mass, body fat, muscle mass, and right and left thigh circumference), physical fitness (power and VO2max), and vascular responses (flow-mediated dilation (FMD), brachial ankle pulse wave velocity (baPWV), ankle brachial index (ABI), systolic blood pressure (SBP) and diastolic blood pressure (DBP)) were measured. The results showed a significant time × group interaction effect on muscle mass (F = 53.242, p = 0.001, ηp2 = 0.664) and right thigh circumference (F = 4.544, p = 0.042, ηp2 = 0.144), but no significant variation in any other factors, including fat mass, body fat, left thigh circumference, FMD, baPWV, ABI, SBP, and DBP (p > 0.05). Overall, our results suggested that eight-week LABFR exerted a positive effect on the body composition, especially muscle mass and thigh circumference, of recreational runners.

OBJECTIVES This study aims to investigate the effects of instrument-assisted soft tissue mobilization (IASTM) on ankle range of motion (ROM) and balance in older women.METHODS The 20 older women with a history of falls participated in the study, and the study subjects were randomly divided into the IASTM group (n=10) and control group (n=10).RESULTS There were no significant interactions between group and time for ankle ROM and functional reach after 8 weeks of IASTM on older women (<i>P</i>>0.05). Meanwhile, there were significant interactions between group and time for one-leg standing and star excursion balance (<i>P</i><0.05), and in particular, the IASTM group had greater improvements compared to the control group.CONCLUSION In conclusion, the regular application of IASTM has been shown to improve the balance of older women with a history of falls.
